21. Building blocks for polymer synthesis by enzymatic catalysis
Sammanfattning : The search for alternatives to oil-based monomers has sparked interest for scientists to focus on the use of renewable resources for energy production, for the synthesis of polymeric materials and in other areas. With the use of renewable resources, scientists face new challenges to first isolate interesting molecules and then to process them. LÄS MER
22. Expanding the Amino Acid Alphabet by Design : Enhanced and Controlled Catalytic Activity in Folded Polypeptide Catalysts
Sammanfattning : This thesis addresses structure and reactivity of polypeptide catalysts in reactions that mimic the hydrolysis of RNA and DNA. A designed helix-loop-helix motif was used as a scaffold where the amino acid residues were systematically varied. LÄS MER
23. Cyclotides evolve : Studies on their natural distribution, structural diversity, and activity
Sammanfattning : The cyclotides are a family of naturally occurring peptides characterized by cyclic cystine knot (CCK) structural motif, which comprises a cyclic head-to-tail backbone featuring six conserved cysteine residues that form three disulfide bonds. This unique structural motif makes cyclotides exceptionally resistant to chemical, thermal and enzymatic degradation. LÄS MER
24. Enzymatic synthesis of lipids containing omega-3 fatty acids
Sammanfattning : Docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are omega-3 fatty acids, which have health promoting effects. Since they are highly prone to oxidation, they should be protected, in particular DHA. LÄS MER
25. Lipase-catalyzed production of structured triacylglycerols
Sammanfattning : Vegetable oils and fats are major energy sources but also play an essential part in the physical and chemical properties of food products. The current change in the climate is affecting harvest yields, leading to a shortage and increased prices of raw materials that are difficult to replace. LÄS MER
